What does volume and mass have to do with flotationn?
The density of an object is its mass divided by its volume. If that is less than the density of water, it will float; if greater it will sink
Why does a log float?
An object will float on water if it has less density than the water. Or than any other liquid on which it is supposed to float.
What has to have more density for an object to float on water the object or water?
Normally the water - to float and object has to displace a volume of water equal to its mass. If its density is greater than that of water, the maximum mass of water it can displace is its own volume which, as the water is less dense that it, will have less mass than the object and it will sink. However, for small light objects the surface tension of water comes into play - it is possible to float a steel sewing needle (with a density greater than water) on water by gently dropping a clean needle on its side onto the water surface so that it does not break the surface tension. With a needle floating, adding a few drops of washing up liquid to the surface reduces the surface tension and the needle will then sink.
How could it be possible that an object with a density greater than that of water could float in water?
There are two ways to make an object with a density greater than water float on it: 1) reduce its density, for example by hollowing it out or adding further structures with a density [much] less than that of water so that it can displace a volume of water equal to its own weight and still have some of its structure above the surface of the water; or 2) Use the surface tension of water so that the object floats - dropping a steel sewing needle on its side very gently onto water will prevent it breaking the surface tension of the water and it will float, until such time as the surface tension is broken, eg by adding a few drops of washing up liquid or agitating the surface, when the needle will sink. (The needle needs to be clean.)
Is sodium density greater less than or equal to water?
At room temperature, the density of sodium is slightly less than that of water and it will, briefly, float (briefly, because it will be rapidly reacting with the water, and may in fact be on fire at the time).
WHAT happens to a solid object with a density that is less than the density of water when it is placed in water?
It floats
What is happens to an object when placed in water if the density is below one?
If an object with a density below one is placed in water, it will float. This is because the density of the object is less than that of water, causing it to be buoyant and float on the surface.
What happens to a solid object with density that is less than water when it is placed in water?
it floats.They float at water surface.
What happens to a solid object when density that is less than water when it is placed in water?
it floats.They float at water surface.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
What would happen if you tried to find the density of an object with a density less than water?
If you try to find the density of an object with a density less than water, the object will float in water. This indicates that the object is less dense than water. To find the density of such an object, you would divide the mass of the object by its volume.
Is it true that when the weight of an object is less than the density of water that object the object will float?
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
How are mass and volume related to the sinking and floating of an object?
An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.
What happens to an object if it has a density that is less than 1 gram?
If an object has a density less than 1 gram per cubic centimeter, it will float in water because the density of water is around 1 gram per cubic centimeter. This means that the object is less dense than water and will displace enough water to stay afloat.
What happens to an object that is placed in water that has a density greater than 1.0 gmL If the density of the object has a density less than 1.0 gmL?
If an object with a density less than 1.0 g/mL is placed in water with a density greater than 1.0 g/mL, it will float. This is because objects with a lower density than water will displace an amount of water equal to their own weight, causing them to float.
How can one determine if an object will float in water based on its density?
An object will float in water if its density is less than the density of water. If the object is denser than water, it will sink.
What is the density of an object to float in water?
An object will float in water if its density is less than the density of water, which is 1 g/cm^3. This means that the weight of the object is less than the weight of the water it displaces, allowing it to float.
